横琴新区环岛西路快速化改造总体方案设计

Overall Scheme Design for Rapid Reconstruction of West Huandao Road in Hengqin New Area

由于部分城市的空间布局受地理条件限制,导致上位规划中快速通道无法实施,退而求其次实施近期方案。但随着城市快速化发展,以及城市空间结构的不断更新,近期方案不能满足城市发展需求,上位规划中的快速通道亟须实施。以珠海市横琴新区环岛西路为例,现状存在山体、河渠等天然瓶颈。为实现现状环岛西路快速化改造,进行多方案比选,通过对实施过程、工程造价等影响因素的分析,确定最优方案,同时为相似道路快速化改造提供借鉴。

As the spatial layout of some cities is limited by geographical conditions,the fast channel in the upper planning cannot be implemented,so the short-term scheme has to be implemented.However,with the rapid development of city and the continuous updating of the urban spatial structure,the short-term scheme cannot satisfy the urban development demand.It is imperative to implement the rapid channel in the upper planning.Taking West Huandao Road in Hengqin New District of Zhuhai City as an example,there are natural bottlenecks such as mountains and canals.In order to realize the rapid reconstruction of the current West Huandao Road,the multiple schemes are compared and selected.The optimal scheme is determined through the analysis of the implementation process,engineering cost and the other influencing factors,which also provides the reference for the rapid reconstruction of similar roads.
